After centuries of plotting, the Sphinx is on the verge of recovering the five artifacts necessary to open the legendary prison. Facing the potential of a world-ending calamity, all friends of light must unite in a final effort to thwart the Sphinx s designs and find a safe home for the five artifacts. To this end, Kendra, Seth, and the Knights of the Dawn will venture far beyond the walls of Fablehaven to strange and exotic magical preserves across the globe, where the end of every quest becomes the beginning of another. In this explosive series finale, allegiances will be confirmed and secrets revealed as the forces of light and darkness collide in a desperate struggle to control the keys to the demon prison. Review: Fablehaven Forever - This is the fifth time I've read Fablehaven and it always saddens me when I reach the end. Its such an engaging book! Filled with so many mystical creatures and animals that I've never even heard of but clearly exist in mythology. The adventures of Kendra and Seth are so imaginative and I have never read any book series that quite matches the fantastical element these books bring. I enjoy it immensely and I will read this series again and again in the future. Review: Well done. A favorite for my 11 year old, 8 year old and me. - We have enjoyed all the books of this series. Some parts of the Fablehaven books, and this book in particular, are blatantly moralistic. A little too blatant for an adult book, but very appropriate for a children's book. I really liked that for the most part because it is a springboard for meaningful conversations with my kids. As for book 5. It is fast paced and engaging. For the past three days my 11 year old daughter has read it every recess and then every spare minute we've had we have sat side by side both reading from our places in the book. I am reading it to my 8 year old son, but it will be another week before the two of us finish. It is a relief to have a book that I not only have NO hesitation recommending for my kids, but one that I WANT them to read because of the good lessons in it AND for its great entertainment value. I think Brandon Mull did a great job leading up to an unexpected conclusion of events for the most part. Aside from two little "tidy" parts near the end (which I don't list for "spoiler reasons") I think everything was done very very well. I even like the loose ends as they lead to great imaginative adventures if you want to continue the story on your own. Bravo! We have enjoyed all of Brandon Mull's books (Pingo included) and look forward to more! ## Features - Used Book in Good Condition ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #43,564 in Books ( See Top 100 in Books ) #24 in Teen & Young Adult Multigenerational Family Fiction #124 in Teen & Young Adult Fantasy Action & Adventure #215 in Teen & Young Adult Wizards & Witches Fantasy | | Customer Reviews | 4.8 out of 5 stars 2,550 Reviews | ## Images ![Keys to the Demon Prison (Fablehaven) - Image 1](https://m.media-amazon.com/images/I/81RJxzlp9ZL.jpg) ## Available Options This product comes in different **Format** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fablehaven Forever *by S***N on June 25, 2025* This is the fifth time I've read Fablehaven and it always saddens me when I reach the end.
